This function seems to work for me:
# filename: the .rdb file
# offset, size: the pair of values from the .rdx
# type: 'gzip' if $compressed is TRUE, 'bzip2' for 2, 'xz' for 3
readRDB <- function(filename, offset, size, type = 'gzip') {
f <- file(filename, 'rb')
on.exit(close(f))
seek(f, offset + 4)
unserialize(memDecompress(readBin(f, 'raw', size - 4), type))
}
